Digital Still Camera Power Supply

General Description

Features

The MAX1565 provides a complete power-supply solution

for digital still and video cameras through the integration

of ultra-high-efficiency step-up/step-down DC-to-DC con-

verters along with three auxiliary step-up controllers. The

MAX1565 is targeted for applications that use either 2 or

3 alkaline or NiMH batteries as well as those using a

single lithium-ion (Li+) battery.

ꢀ Step-Up DC-to-DC Converter

95% Efficient

3.3V (Fixed) or 2.7V to 5.5V (Adjustable) Output

Voltage

ꢀ Step-Down DC-to-DC Converter

Operate from Battery for 95% Efficient Buck

Combine with Step-Up for 90% Efficient Buck-

Boost

The step-up DC-to-DC converter accepts inputs from

0.7V to 5.5V and regulates a resistor-adjustable output

from 2.7V to 5.5V. It uses internal MOSFETs to achieve

95% efficiency. Adjustable operating frequency facili-

tates design for optimum size, cost, and efficiency.

Adjustable Output Down to 1.25V

ꢀ Three Auxiliary PWM Controllers

ꢀ Up to 1MHz Operating Frequency

ꢀ 1µA Shutdown Mode

The step-down DC-to-DC converter can produce output

voltages as low as 1.25V and also utilizes internal

MOSFETs to achieve 95% efficiency. An internal soft-

start ramp minimizes surge current from the battery.

The converter can operate from the step-up output pro-

viding buck-boost capability with up to 90% compound

efficiency, or it can run directly from the battery if buck-

boost operation is not needed.

ꢀ Internal Soft-Start Control

ꢀ Overload Protection

ꢀ Compact 32-Pin, 5mm x 5mm Thin QFN Package

The MAX1565 features auxiliary step-up controllers that

power CCD, LCD, motor actuator, and backlight cir-

cuits. The device also features low-cost expandability

by supplying power, an oscillator signal, and a refer-

ence to the MAX1801 SOT23 slave controller that sup-

ports step-up, SEPIC, and flyback configurations.
